The viewer's attention is usually not drawn to the ear region of the human anatomy very often. If there is one portion of the human anatomy that is rarely brought to their attention, it would have to be the ears. So, [DIY GUY Chris] has designed some LED earringsthat should accomplish this very task.
PCBs are used throughout the entire construction process of the earrings, making them the primary component of the earrings' bodies. Each of the printed circuit boards that go into making an ear contains a total of eight WS2812 LEDs, all of which have a size factor of 2020.
The LEDs receive their instructions from an ATtiny13-A AVR microcontroller, which is responsible for their operation. In addition, certain supplementary hardware is essential in order to guarantee that everything will operate as it should when brought together.
Each earring is powered by a single CR1220 coin cell, which is hidden on the obverse side of the earring so that the wearer does not see it when they are wearing the earrings.

Pogo pins, rather than any other cumbersome connectors, are utilized in the programming of the earrings due to the fact that this removes the prerequisite for their utilization.
Due to the fact that the LEDs are so small and can be managed on an individual basis, the earrings are able to display the whole RGB color gamut. DIY Guy Chris has programmed the earrings such that they have some straightforward color fades in addition to some more involved chase animations.
First, you need to have these required itemsfor producing the earring:
- The customized PCB design
- ATtiny13A-MMU AVR Microcontroller
- 8 x WS2812-2020 Addressable RGB LEDs
- 100 nF ceramic capacitor 0402
- SMD Slide switch
- CR1220 Coin Cell Battery holder
- Step 1 - The Circuit Design
- Step 2 - Circuit Board Assembly
- Step 3 - Code and Final Test
